Having described my invention I claim as new and desire to secure by Letters Patent:

1 In a pulverized fuel burner, in combination, two co-axial air-carrying pipes, two

(-o-axial discharge nozzles, one for each pipe and spaced ball-and-socket jointed connections between the nozzles and the respective pipes, providing for separate control of the contents of the two pipes, as far as the end of one of the nozzles,

2. In a pulverized fuel burner, in combination, two pipes adapted to carry air at different pressures and'one within the other, a nozzle for each pipe, the inner nozzle being shorter than the outer nozzle, a ball andsocket jointed connection between each pipe and its nozzle, the inner connection being supported by, and spaced from the outer connection and common. means for tightening both connections in adjusted position.

3. In a pulverized fuel burner, in combination, an outer pipe, an inner pipe co-axial therewith, outer and inner co-axial nozzles, joint members upon the pipes and nozzles cooperating to unite the outer and inner pipes to the outer and inner nozzles, respectively tension means, acting across one of the joints for retaining its jolnt members in connection. 4. In a pulverized fuel burner, in combination, a pair of .co-axial air-carrying pipes,

a pair of co-axial nozzles for the two pipes, a ball and socket connection between each of the nozzles and its pipe, providing space for air passage between the connections and be tween the nozzles, support for the inner nozzle and connection from theouter nozzle and connection, and exterior means for tightening the two connections, adapted to move each nozzle. toward its pipe. 1

emme 5.. In a pulverized fuel burner, in combination, a pair of co-axial pipes, one within the other, a spaced mechanically-connected pair of nozzles, one for each pipe, a universal joint connection between each nozzle and its pipe and tension members, secured to opposite sides of one of the universal joints, adapted to hold the two joints in adjusted position. x

6. In a pulverized fuel burner, in combination, a chamber closed at one end and open at the other, a secondary air pipe discharging in the said chamber, a discharge nozzle for said chamber, a ball and-socket jointed connection between 1 said nozzle and said chamber, a primary air pipe entering said chamber, at its closed end, a second discharge nozzle, flared and entering the first nozzle and movable with the first discharge nozzle, and a ball and-socket jointed connection ond ball-and-socket jointed connection unitingv said primary air pipe and second nozzle and providing space between the two jointed connections.
